2 Claims.

I This application is a division of my application Serial No. 393,016, filed June 30, 1920 for Roofing materials, which matured on March 15, 1932 into Patent No. 1,849,869.

The invention relates to sheet roofing materials, strip shingles and the like, or other surfacing materials of this general class, and has special 'reference to the means provided upon or for use in connection with such materials, through which ttmdapt certain areas of the material for seaming or jointing with or adhering to the building structure or other portions of the material with which it may be associated in use.

Accordingly, the invention consists primarily in providing a mastic joining strip, or other suchlike means, adapted for application to the roofing material to serve as a cementing element, packing In order that the invention may be fully understood several embodiments thereof are disclosed by way of illustration in the accompanying drawing.

In said drawing- Figure 1 represents the use of the invention as a combined base and binder for shingle strips of flexible material.

' Figures 2 and 3 show modifications of the invention. 1 represents a sheet of roofing material, .which, according to Figure 1 is equipped with a mastic material which carries it and permitted to overhang in a manner to enter into similar relation to an abutting or flush jointed sheet, and thus produce a waterproof connection. One edge of strip 2 may preferably be serrated or slotted at spaced intervals to provide a series of spaced tabs.

As shown in the drawing, this method of applying a mastic strip has special advantages in connectionwith shingle strips, where the strip 2 is I pose of providing a base for each shingle strip, and

applied in such widththat it will overlie the major portion of a shingle strip, including that portion thereof which overlies the upper edge of the next lower shingle strip, so that it serves a double purparticularly the serrated or slotted portions thereof which form the tabs of theshingles, and also cements these tabs to the underlying continuous portion of the shingle strip and furnishes the surface coloring or contrasting surface between the shingle tabs. In practice this joining strip will be,superimposed upon the upper surface of the continuous part of the shingle strip and permitted to extend beyond the same, so that it will enter into the relations described, and perform all of the functions above enumerated by the mere act of overlapping it'with the tab portion of the succeeding shingle strip when the roof is laid.

The various forms of joining strips herein described may be marketed in proper form for application to the roofing sheet, as, for instance, by rolling the strip and shipping it in suitable wrappers, but it is preferably applied to the sheet in the factory.

The mastic with which the seaming or joining strip is impregnated may be of varying character according to the method of using it. It may have the inherent quality of lasting stickiness or adhesiveness so that when exposed it renders the roofing material immediately self adhering; or it may be compounded more with a view to affording a packing substance between overlapped sheets of material so as to render weatherproof a joint that is primarily held by nailing; or it may'contain a non-drying oil which will be given off gradually into the impregnating substance of an overlying sheet with the effect of dissolving such substance and developing a gradual cementing action at the joint; or it may be of such nature that it will be normally non-adhesive, but it may be readily rendered adhesive by painting over its exposed surface a suitable, reagent that will sufliciently dissolve it to cause it to adhere to contacting surfaces. This latter method may likewise be applied to arch of the seaming tape or strip just previous to putting it into use.

Mastics having the inherent quality of adhesiveness when in normal state and suitable for rendering roofing or other sheet surfacing material self adhering without the use of heat or other media at the time of applying the surfacing material to its place of use, are readily obtainable from dealers in the open market when specified in terms of function to be performed.

They may also be found specified in terms of function to be performed. Among the mastics or normally sticky and tacky adhesives which are substantially lastingly adhesive and slowdrying in nature to be found on the open market, and which have been purchasable on the open market long prior to the year 1918, may be mentioned various bituminous adhesives, for instance, the asphaltic departments of the leading petroleum companies of the United States have these adhesives on sale. I have in mind a bitumi-' nous adhesive sold by the Texas Company of the United States, known as Texaco 12/145 Gravity Flux. This and substantially identical bituminous adhesives have been known for many years and have been constantly sold and are now sold in the open market, and may be obtained by merely describing the characteristic forth in this application.

Figures 2 and 3 show modifications similar to the strip shown in Figure 1, and in which the strip is not only in position to close the seam between two abutting roofing members, but is also of such design upon its other surface as to lend a distinctive effect to the appearance of the roof.

The strip 2 may consist of an elongated piece of paper, felt, fabric, or even mastic withra fibrous or other vehicle incorporated therein, or,.in fact, any body of material that can be fed from a suitable source in the form of a strip and laid upon and caused to adhere to the roofing sheet.

qualities set sealing strip comprising a body portion serrated on the projecting side to form a series of tabs.

2. A roofing sheet of flexible material comprising a base, a' slab attached to the base and projecting therefrom to overlap the base of an abutting strip, and a series of tabs formed on the slab to provide a decorative design on the weather exposed surface.
